+**Apache mod_proxy library:** The ability to use Apache as a reverse proxy is provided through a shared library named mod_proxy.so. This module is not enabled by default, so you must edit Apache’s httpd.conf file to enable it. You also need to enable Apache’s mod_proxy_http.so shared library.
+**Enable the mod_proxy and mod_http modules in Apache’s httpd.conf file.** Uncomment the appropriate lines in Apache’s httpd.conf file to enable the Apache mod_proxy and mod_proxy_http modules.  **Note that this may not apply to newer versions of Apache2 and Ubuntu.  SEE BELOW**
+<code>
+### Enable LoadModule entry for Apache mod_proxy and mod_proxy_http ###
+#LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so
+LoadModule proxy_module modules/mod_proxy.so
+LoadModule proxy_http_module modules/mod_proxy_http.so
+#LoadModule proxy_scgi_module modules/mod_proxy_scgi.so
+</code>
+Instead, maybe enable the appropriate apache proxy modules, and restart apache server:
+<code>
+sudo a2enmod proxy
+sudo a2enmod proxy_http
+sudo systemctl restart apache2
+</code>

+Configure apache2
+Apache2 is configured by placing directives in plain text configuration files in /etc/apache2/. These directives are
+separated between the following files and directories:
+Files
+• apache2.conf
+The main Apache2 configuration file. Contains settings that are global to Apache2.
+Note: Historically, the main Apache2 configuration file was httpd.conf, named after the “httpd”
+daemon. In other distributions (or older versions of Ubuntu), the file might be present. In modern
+releases of Ubuntu, all configuration options have been moved to apache2.conf and the below referenced
+directories and httpd.conf no longer exists.
+• envvars
+File where Apache2 environment variables are set.
+• magic
+Instructions for determining MIME type based on the first few bytes of a file.
+• ports.conf
+Houses the directives that determine which TCP ports Apache2 is listening on
